Bradford Industrial Museum - It always amazes me to see the huge variety of cogs and wheels in the machinery in the museum. I notice new variations each time I go. I like the different patterns and colours in the top image; three wheels, all different, all with a specific purpose.
The machine below was painted in muted greeny-brown colours but the red disc really stood out. I wondered if there was a reason this piece was painted red - danger, maybe? Seemed to cry out for a mono conversion and a colour-pop!
